I have found that others reviews are somewhat correct. The holster can definitely use some tweaking...it does not put the phone to sleep as the magnet is no where near capable enough to penetrate the case or reach the phone's magnetic shutoff. It also has some design flaws wherein it doesn't hold the phone adequately...you're more likely to lose the phone than incur any damage to it. The design of the case also hinders the use of the touch screen. This phone relies on swipe gestures that are made quite difficult with this case on...not impossible, but difficult for new users. The screen protection also lets in too much debris in behind it as a result of the large upper cutout for the speaker and camera. This being said, I am more than satisfied with the case. I work in demolitions and need sturdy protection for my phone. This case handles that and more. I have dropped my phone from >25ft onto hard surface with no damage to the phone. My Z10 receives daily rough treatment without causing worry about its safety. This case has saved my phone on numerous occasions and I would say it has been a very good investment. I have gotten used to the case design flaws in using swipe gestures as I have been using this case for the past 4 months but it did take me a couple weeks to get used to using my phone with the case on.
